wpa_supplicant 输出中的“由于与 WPA/WPA2 不匹配而拒绝”是什么意思？

我正在尝试连接到一个设置为 wifi 网络共享的 Android 4.0.4 设备，wpa_supplicant使用/etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant
ap_scan=1

network={
    ssid="STYLUS iDroid SP 1001"
    scan_ssid=1
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP
    group=TKIP
    psk="foobar"
}

以及设备上的此 SSID 和此 WPA2-PSK 密码。在输出中，wpa_supplicant我发现

     53 54 59 4c 55 53 20 69 44 72 6f 69 64 20 53 50   STYLUS iDroid SP

我怀疑“拒绝与 WPA/WPA2 不匹配”应该解释一下这个表述有什么问题，但正如许多其他表述一样，它既无用又不言自明。它是什么意思？

network-manager-gnome当我在 Ubuntu 14.04 中使用 (0.9.8.8-0ubuntu4.3) 的小部件（意味着停用该界面）时，连接有效/etc/network/interfaces。

答案1

根据这篇文章，你的 ssid 中​​没有空格可能会有帮助。

https://android.stackexchange.com/questions/1494/wifi-wont-connect-when-ssid-has-space-character

当我看到你的 ssid 中​​有空格时，我感到很奇怪，所以我在 Google 上搜索了它是否允许，结果是允许的，但从我读到的内容来看，它可能会导致问题。上面的链接就是一个例子。

答案2

注释掉proto，key_mgmt（如@muru 所建议的）并group让它们自动检测解决了该问题（这可能是network-manager-gnome小程序和/或network-manager所做的）。
